Photobiomodulation Therapy for Serous Pigment Epithelium Detachment in Chronic Central Serous Chorioretinopathy.

Purpose: To report a case of giant pigment epithelium detachment (PED) secondary to chronic central serous chorioretinopathy (cCSC) successfully treated with photobiomodulation (PBM).

Methods: Case report.

Results: A 55-year-old man complained a worsening of vision in the left eye (LE) over the last 18 months.A complete ophthalmological evaluation encompassing best corrected visual acuity (BCVA) measurement, spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), fluorescein angiography (FA) and microperimetry (MP) was performed.SD-OCT showed several small PEDs around the macula in the right eye and a giant macular serous PED with subretinal fluid (SRF) in the LE. FA disclosed multiple hyperfluorescent roundish areas in the posterior pole bilaterally, with a macular pooling in the LE.A diagnosis of cCSC was made, and patient underwent PBM with one session for week for four weeks, followed by one session bi-weekly for two months.SD-OCT of the LE showed a gradual flattening of the macular PED at 3 months, with a complete regression of the latter and of the SRF at 6- and 12-month follow up with no residual signs of chorioretinal atrophy on FAF. BCVA improved from 20/80 at baseline to 20/25 at the last follow up, and this functional improvement was further confirmed by MP.

Conclusions: PBM can be considered a safe and effective treatment strategy for the management of cCSC with SRF and serous PED.
